Visto Receives Prestigious Deloitte Technology Fast 50 Award

Rapid growth in revenue and subscribers places company at the forefront of Silicon Valley success

Redwood City, California, November 6, 2007 – Visto, the leading global provider of secure, easy-to-use mobile email, today announced it has been named to Deloitte's prestigious Technology Fast 50 Program for Silicon Valley. The Technology Fast 50 is a ranking of the fastest growing technology, media, telecommunications, and life sciences companies in the region by Deloitte & Touche USA LLP, one of the nation’s leading professional services organizations. Rankings are based on the percentage revenue growth over five years from 2002–2006.

Brian Bogosian, Visto's chairman, president and CEO, credits Visto’s success to its advanced technology optimized to work on most smartphones and relationships with many of the world’s largest and most successful carriers, which has increased the subscriber base by 250 percent over the last 18 months and the company’s revenue by more than 1200 percent in the last five years. Visto has partnered with leading mobile operators worldwide to offer the company’s flagship product, Visto Mobile™ with the service plans and devices that make mobile email accessible to all individuals – not just the top-ranking executives.

“We are honored to be recognized by Deloitte’s Technology Fast 50 Program, which is a testament to our team, our technology and to our partners who have sold our products to their subscribers worldwide. Deloitte’s selection of Visto is based on the cold hard facts of growth and revenue,” said Bogosian.  “The market for mobile email on non-Blackberry devices has grown rapidly over the last five years, and Visto has led the growth in this market.  Our rapid expansion in more than 20 countries is indicative of the strength of the company and our compelling market proposition, as the global demand for mobile email expands to hundreds of millions of users.”

“Deloitte’s Silicon Valley Technology Fast 50 companies have shown the strength, vision and tenacity to succeed in today’s very competitive technology environment,” said Mark Jensen, partner and national director, Venture Capital Services, Deloitte & Touche LLP.  “We applaud the successes of Visto and acknowledge it as one of the very few to accomplish such a fast growth rate over the past five years.”
